Went away for a week and for the first time ever, I turned off the electric pump for the shower from the switch outside the hot-press.Came back, turned on switch, and pump now not working.Checked fuse - it is fine.I believe there is a ''reset switch'' somewhere on the pump, but, of course, I don't have the manual.

Hey TomHow did you get on in the end with the pump? Mine's giving me problems now. It keeps cutting in and out and I have to reset it by switching it off, opening all the taps in the bathrooms and then switching it back on. Seems to work okay then but appliances can't be left unsupervised as the pump stops and then they stop and then the pump seems to heat up to some incredible temperature! Can you recommend someone who you used to fix it?Thanks!

Thanks! I had to get the PCB and capacitor replaced. Apparently the pump being connected to the appliances is the issue. The pumps were not designed for that but they were connected that way for simplicity. Hope this helps.

Hi AshM, would you mind sharing the cost of the overall repair with others just for awareness ? Did you sort it out yourself or did you deal with the manufacturer directly ?

Of course. The whole thing cost EUR170 including the pump maintenace people coming in to fit it for me. I'm not as handy as some here so I wouldn't even know where to start to fix it myself. The whole thing only took about 20 minutes. I told them I wanted it repaired as opposed to replaced. I heard that some plumbers know this is an issue with these pumps and will insit on replacing the pump, take the old one away, replace the PCB and capacitor themselves and sell them on or replace them as new pumps in other homes.

I went to The Shower Doctors who were very professional and have the maintenance contracts for the Stuart Turner pumps in Dublin: http://www.theshowerdoctors.ie/pumps. I called them on a Thursday and they arranged a time with me for Monday afternoon.

One more thing. The Guy who fixed it for me says that the PCB comes with the capacitor and if you're replacing the PCB you should replace the capacitor as it's sold as one unit as such. Obviously, being a Girl, I could be told anything that suits so you can disregard this info if you don't think it's relevant.

Thanks for sharing the information. It just confirms the quote I received from Chris from Modern Plant a while ago (Maintenance cost between 140-180). Indeed the Shower Doctors are the maintenance contractor for Modern Plant. They charge a callout charge + labour + parts. Since the PCB costs €45 and capacitor costs no more than €10, I thought at the time that €125 callout+labour was still high in these circumstances.

As for the PCB and Capacitor, this is wrong but you could have a different model. I replaced my capacitor without having to solder it and it was separate from the PCB. It was an easy job anyway and it only took a few minutes.

Just wanted to say thanks for all the detail here. We've had this exact issue for the best part of a year and were worried that we'd have to replace the system. Following the advice here though, we contacted the Shower Doctors and a day later they had a guy here to replace the PCB and the Capacitor. Apparently the pump itself is fine but the PCB is not suitable for supplying the showers and the kitchen machines. But the new PCB has a transistor and is better equipped to deal with the problem (probably why the wiring was tricky). 170 euro and (fingers crossed!) the issue is sorted with a one year guarantee on the parts!
